About Us

We are an emerging startup building an AI-powered video creation platform that runs

across Telegram and the web, enabling users and clients to generate customised AI

videos effortlessly.


Using advanced tools like LoRA, text-to-video, and image-to-video models —

orchestrated through ComfyUI or equivalent pipelines — we’re creating a platform where

creativity meets automation.


We’re looking for a Full-Stack AI Video Platform Developer who can build the entire

system end-to-end, from backend AI workflows to frontend user experience — both on

Telegram and on a web platform.


Key Responsibilities

1. System Architecture & Workflow Integration

• Design and implement the complete AI video workflow, integrating LoRA, text-to-

video, and image-to-video pipelines using ComfyUI, or other custom AI backends.

• Ensure smooth model orchestration, GPU job scheduling, and scalability for video

generation.

• Integrate AI models into a flexible backend that supports user-specific

configurations, custom LoRA uploads, and prompt-driven video outputs.


2. Backend Development

• Build a robust backend (Python / Node.js) for managing video generation requests,

AI model orchestration and media output delivery.

• Create RESTful APIs or GraphQL endpoints for both the web frontend and

Telegram bot.

• Handle database architecture (PostgreSQL, Redis or equivalent) for user

accounts, LoRA metadata, generation history, and video assets.

• Manage GPU servers or cloud instances (AWS / RunPod / Hyperbolic labs/ Others

equivalent) for AI workloads.


3. Frontend Development (Web Application)

• Develop a modern, responsive web platform that allows users to:

o Create video generation tasks using text or images

o Upload and manage custom LoRA models

o Monitor video generation progress

o Preview and download generated videos

• Build the frontend using frameworks like React, Next.js, or Vue.js, with a focus on

usability and performance.

• Implement authentication systems, dashboards, and intuitive user workflows.

• Collaborate on the UI/UX design to ensure a seamless creative experience.


4. Telegram Bot Development

• Develop a Telegram bot interface that mirrors the web platform’s functionality for

users who prefer chat interaction.

• Implement workflows for users to input prompts, upload images or LoRAs, and

receive generated videos directly in chat.

• Ensure Telegram and web users share the same backend and database ecosystem.


5. AI Model Management & Customisation

• Integrate, fine-tune, and manage LoRA and diffusion-based models to support

custom video generation.

• Ensure reproducibility, quality control, and versioning of all models used.

• Continuously explore and integrate new AI video generation models and

technologies.


6. Infrastructure, DevOps & Maintenance

• Manage deployment and scaling using Docker & CI/CD pipelines.

• Implement robust logging, error handling, and monitoring systems.

• Ensure secure storage of user data, videos, and LoRA files.

• Maintain uptime, optimise performance, and manage storage efficiency.
